Salah completed his hat trick by keeping cool in front of goal after a mazy dribble to complete the rout in the 77th.
"Whatever you do in a football game, you need someone to finish it off, and what Mo did around his two goals in the second half is just exceptional," Liverpool manager Juergen Klopp said. "I don't know many players who would score those two goals. The first in the second half was a foul actually but he wants to score, stays on his feet and still scores. Not the most impressive finish, but surprising."
Liverpool equaled its club record of 17 Premier League matches unbeaten. Now the five-time European champions have a must-win match at home to Napoli on Tuesday to advance to the Champions League round of 16.
